Which of the following is an example of Keyword search

Explanation:

Just like a keyword is a single word used as a search query, a keyword phrase is two or more words typed as a search query. For example, Poughkeepsie classic car customization is a good example of a keyword phrase. ... Usually when people do a search, they type in a keyword phrase instead of just a single keyword.

wheres the options? i dont think this can be solved with out the options

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
